## NAME

           add_wchstr,    add_wchnstr,   wadd_wchstr,   wadd_wchnstr,
           mvadd_wchstr, mvadd_wchnstr, mvwadd_wchstr, mvwadd_wchnstr
           - add an array of complex characters (and attributes) to a
           curses window

## SYNOPSIS

           #include <curses.h>

           int add_wchstr(const cchar_t *wchstr);
           int add_wchnstr(const cchar_t *wchstr, int n);
           int wadd_wchstr(WINDOW * win, const cchar_t *wchstr);
           int wadd_wchnstr(WINDOW * win, const cchar_t *wchstr, int n);
           int mvadd_wchstr(int y, int x, const cchar_t *wchstr);
           int mvadd_wchnstr(int y, int x, const cchar_t *wchstr, int n);
           int mvwadd_wchstr(WINDOW *win, int y, int x, const cchar_t *wchstr);
           int mvwadd_wchnstr(WINDOW *win, int y, int x, const cchar_t *wchstr, int n);

## DESCRIPTION

           These routines copy the array of complex characters wchstr
           into  the  window image structure at and after the current
           cursor position.  The four routines with  n  as  the  last
           argument  copy  at  most n elements, but no more than will
           fit on the line.  If n=-1 then the whole array is  copied,
           to  the  maximum number of characters that will fit on the
           line.

           The window cursor is not advanced.   These  routines  work
           faster than waddnstr.  On the other hand, they do not per-
           form checking (such as for the newline, backspace, or car-
           riage  return characters), they do not advance the current
           cursor position, they do not expand other control  charac-
           ters  to  ^-escapes,  and  they  truncate the string if it
           crosses the right margin, rather than wrapping  it  around
           to the new line.

           These  routines  end  successfully  on encountering a null
           cchar_t, or when they have filled the current line.  If  a
           complex  character cannot completely fit at the end of the
           current line, the remaining columns are  filled  with  the
           background character and rendition.

## NOTES

           All functions except wadd_wchnstr may be macros.

## RETURN VALUES

           All routines return the integer ERR upon failure and OK on
           success.

## PORTABILITY

           All these entry points are described  in  the  XSI  Curses
           standard, Issue 4.
